Then it makes absolutely no difference what we do on earth. Therefore you can either a.) accept that as fact and do whatever pleases you or b.) reject that notion and live a righteous life in the hopes of a blissful life after death.
Well that would be really cruel and our heavenly Father is not a cruel God. In fact, the teaching of Hellfire as punishment for the sinful is not supported by scripture. The Bible says at Ecclesiates 3:19, 20 man returns to dust and at Romans 6:23 the wages sin pays is death. No parent would dare burn their child, why would or Creator Jehovah, who's love far passes anything we could imagine as humans. Also it is impossible for anyone to continually burn. As for hell and hades mentioned in the Bible, it is refering to the grave of mankind. Even Jesus was spoken of as going there. Hope this gives some relief. :) Jw.org
